Amos Dudley, a broke undergrad, casted a mold of his teeth using "cheap alginate powder, Permastone, and a 3d printed impression tray," then 3D printed and vacuformed a series of alingment trays for a fraction of what it would have cost to get name-brand invisaligns.
Obviously, this only works if you have ready access to "knowledge of orthodontic movement, a 3D scanner, a mold of the teeth, CAD software, a hi-res 3D printer, retainer material, and a vacuum forming machine."
But if you do, it doesn't look all that challenging to roll your own alignment trays.
Interestingly enough, a fight over precisely this kind of thing may destroy the Internet.
So what does one need to do this themselves? Knowledge of orthodontic movement, a 3D scanner, a mold of the teeth, CAD software, a hi-res 3D printer, retainer material, and a vacuum forming machine. I realized, I had - or could acquire - all of these things. I have my own 3D printer, but the dimensional accuracy isn’t good enough. NJIT has a digital fabrication lab with a Stratasys Dimension 1200es. That would do the trick. I tested the machine, and found it could give me X,Y accuracy under .1mm, which was close enough. I think a stereolithography printer like a Formlabs Form2 would have been even better, since they have vast X,Y resolution and accuracy. Vertical print resolution didn’t matter much- the direction of motion was in X and Y, not Z. The same lab also has a vacuum forming machine, and some NextEngine laser scanners.
Orthoprint, or How I Open-Sourced My Face
On March 19, Tor Books will release my next book, Radicalized, whose four novellas are the angry, hopeful stories I wrote as part of my attempt to make sense of life in our current moment.
My most recent essay film, Visual Disturbances, premiered in the open access journal [in]Transition yesterday. This open access journal features peer reviewed academic video essays and showcases a wide variety of film and media analysis. Visual Disturbances uses some cutting-edge eye tracking visualizations to explore how film audiences both perceive and mis-perceive movies.

It’s a rude awakening for that rookie vacationer abroad when they try to plug in their gear for the night. Veteran jet-setters know that outlet shapes can vary wildly from country to country, which necessitates that most boring must-have for any world-traveler: A sackful of clunky power adapters. Awkward problem, elegant solution: The Twist Plus […]

The graveyard of failed startups is littered with concepts that just got lost in translation. At its core, that’s what great front-end design is about: Making an app or website usable, translating its best ideas smoothly to the user. It’s a skill so broad there might be no one book or course that covers it […]
